The CN991 and CN992 units shown above were actually built for the London & Port Stanley Railway in London Ontario Canada. Many of you know me for my MSTS representation of that line which included models of these locos. The L&PS was an electric railway for most of the early 1900's. In the early days electricity ran at 25 Hertz not the 60 Hz of today. And the L&PS was designed for that 25 Hz power. Eventually Ontario transitioned to the 60Hz system, which actually meant going house by house and providing replacement appliances for anything that wouldn't work on 60Hz. But Ontario hydro kept one 25Hz generator running at Niagara Falls to power the old L&PS equipment. In the 1950's Ontario Hydro gave notice to the L&PS that the last 25Hz generator was being shut down. This precipitated the ordering of two new diesel loco's to replace the old traction units. These were L4 and L5, made in 1955 by General Motors right in their London Ontario factory. The choice of the G12 was mainly due to weight. The L&PS ran on 70 pound rail with light weight bridges which couldn't withstand the load of the heavier loco's. I think these may have been the only G12's to operate in Canada. They last operated on Vancouver Island. I wonder where they are now?
The units from what I once read and have seen photos, were re-trucked (narrow gauge) and sent to Newfoundland in the later 1970s to run on CN's operation there which also ran similar but different units. It appears they did not survive long and were used for parts.
